4sensitivities described in

13\protect \ref{sec:results},
14  i.e.\ including buildings and a friction value of 0.01.
15  The seaward boundary condition is as
16  provided by the \textsc{ursga} model. The left image shows the maximum
17  modelled depth while the right hand image shows the maximum modelled
18  flow velocities.}

28\caption{Model results for different values of Manning's friction
29  coefficient shown to assess sensitivities.
30  The reference inundation extent for a
31  friction value of 0.01 is shown in Figure
32  \protect \ref{fig:reference_model} (left).  The left and right images
33  show the inundation results for friction values of 0.0003 and
34  0.03 respectively. The inundation extent increases for the lower
35  friction value while the higher slows the flow and decreases the
36  inundation extent. Ideally, friction should vary across the entire
37  domain depending on terrain and vegetation, but this is beyond the
38  scope of this study.}

64  The reference inundation extent is shown in Figure
65  \protect \ref{fig:reference_model} (left).  The left and right images
66  show the inundation results if the wave at the \textsc{anuga} boundary
67  is reduced or increased by 10 cm respectively. The inundation
68  severity varies in proportion to the boundary waveheight, but the
69  model results are only slightly sensitive to this parameter for the
70  range of values tested.}

97  model (Figure \protect \ref{fig:reference_model}) which includes
98  buildings in the elevation data. The right hand image
99  shows the result for a bare-earth model i.e. entirely without buildings. 
100  As expected, the absence of
101  buildings will increase the inundation extent beyond what was
102  surveyed.}
